Description
- The present invention relates to an apparatus for the treatment of water according to the preamble of
claim 1. - Ultraviolet radiation for the treatment of water utilizes an elongated radiation source in the form of an elongated ultraviolet lamp located within a quartz sleeve. In domestic water treatment units, the lamp and sleeve are typically located within a tube or housing through which the water to be treated is passed.
- The sleeve needs to be supported within a closed vessel system to avoid mechanical breakage. Typically, single ended sleeves are supported on the inlet section of these mentioned vessels. In particular (but not only) single lamp reactor systems benefit from any turbulent flow to increase retention time.
- It is known the use of diffuser plates to impart turbulence and rotational flow of water within the vessel, to improve the uniformity and predictability of the treatment of the water. Further known are the use of a fin to impart turbulence to water as it flows into the annular chamber of a water treatment unit and water treatment devices having an inlet baffle plate with orifices.
- It is an objective of the present invention to provide an apparatus for treatment of water with a quartz sleeve support, which is cheap, less complex and allows easy installation.
- This problem is solved by an apparatus with the features listed in claim Accordingly, an apparatus for the treatment of water is provided, said apparatus comprising:
- an elongated housing having a first end and a second end, said first end having a water inlet and said second end having a water outlet;
- an elongated ultraviolet radiation source with a sleeve located within the elongated housing, said elongated ultraviolet radiation source having at its first end electrical connections, which extend through said second end of the housing and having a second free end, and a support element supporting the second free end, wherein the support element comprises a supporting structure containing a ring element and from thereon radially inwardly extending and resiliently deformable arms, wherein the second free end is resiliently held by the arms.
- Additional quartz sleeves surrounding the UV lamp are not mandatory. Therefore, the word "sleeves" should be understood in such a way that when no additional quartz sleeve is present, the glass of the UV lamp (lamp body) itself is the sleeve. The glass of the lamp is likewise made of quartz material.
- The word "held" should be understood so that the arms are pressed against the conical part or the tapered end portion of the free end. This quartz sleeve support has a very simple but effective design. It is advantageous, if the arms are only pressed against the tapered end portion of the free end, so that the sleeve is retained in its longitudinal position.
- Preferably the arms are designed in such a way that during assembly the arms are resiliently deformed and wherein if assembled the arms are pressed against the sleeve, so that the free end of the ultraviolet radiation source is held by the arms in a resilient manner.
- Preferably, the diameter of the sleeve is between 40% and 60% of the diameter of the ring element. Advantageously, the arms are arranged equally spaced in peripheral direction of the ring element. For simplicity and uniform distribution of force, it is preferred that the arms are oblong and equally shaped. In addition it is favourable, that in a relaxed state of the arms the inner ends thereof form a substantially circular opening with a diameter less than the diameter of the sleeve. To the best advantage, the supporting structure has at least six arms.
- In a preferred embodiment the supporting structure has spacers extending radially outward of the ring element. Advantageously, the spacers are arranged equally spaced in peripheral direction of the ring element and the free circumferential surface of the ring element predominates.
- In another favourable embodiment the support element comprises flaps arranged on arms, which extend radially outward of the ring element.
- In running state the flaps are preferably angulated, so the flaps do not radially project over the supporting structure. Advantageously, the flaps are arranged at the arms at about half their length. Preferably, the arms are essentially rectangular with an oblong shape. It is beneficial, if the support element has at least four flaps, each arranged on one arm, wherein the arms are equally distributed along the circumference. To the best advantage the support element is a one-piece stamped-bent part.
- The ultraviolet radiation source, the sleeve and the support element are preferably arranged concentrically.
- Preferred embodiments of the present invention will be described with reference to the drawings. In all figures the same reference signs denote the same components or functionally similar components.

On the outlet side theUV lamp 5 is support by a bushing 7 and is provided with electrical connections. On the inlet side theUV lamp 5 is supported by asupport element 8. Thesupport element 8 is provided with acircular opening 9 through which thequartz sleeve 6 passes. - As shown in
figure 3 , thesupport element 8 has two functional elements: a supportingstructure 10 containing aring element 11 and from thereon radially inward runningarms 12, wherein thearms 12 are spaced equally in peripheral direction and to disturb laminar flow of the water four ormore flaps 13 on the inlet side. - The
arms 12 are essentially rectangular and have an oblong shape. The inner ends 12' of thearms 12 form a substantiallycircular opening 14. The diameter of thecircular opening 14 is less than the diameter of thequartz sleeve 6 and thequartz sleeve 6 can be inserted into theopening 14 by bending thearms 12. Thearms 12 can also be pre-angulated according to thequartz sleeve 6 diameter. The supportingstructure 10 is resilient and absorbs movement e.g. vibrations of the UV lamp. Thearms 12 can press against thequartz sleeve 6 at the tapered end portion of the free end, so that theultraviolet radiation source arms 12 press against the free end of thequartz sleeve 6 at the cylindrical part thereof, so that theultraviolet radiation source - The
flaps 13 are arranged on arms 13', which extend radially outward of the supportingstructure 10, e.g. thering element 11, and are arranged equally spaced in peripheral direction. In case of the shown embodiment, each arm 13' holds asingle flap 13. The arms 13' are essentially rectangular and have an oblong shape oriented in radial direction. In running state the arms 13' are angulated away from the distal free end 6' of thequartz sleeve 6, in reverse direction of water flow. In this state, the arms 13' form spacers, which slightly extend radially outward of thering element 11. Theflaps 13 are as well essentially rectangular and have an oblong shape. Their width is about twice as wide as the width of the arms 13'. Theflaps 13 are arranged at the arms 13' at about half their length. The length of the arms 13' is roughly the same as the length of theflaps 13. Theflaps 13 are preferably bent inward so that theflaps 13 do not project over thering element 11 and/or the spacers. Theflaps 13 are arranged perpendicular to the water flow, increasing the disruption of flow. The consequence is that the flow of water is turbulent and more effective treatment of microorganisms in the water may be achieved. - The invention is not limited to a specific amount of
flaps 13. The design of theflaps 13 and their arms 13' as well as their orientation, e.g. angle, can vary. -
Figure 4 shows a second embodiment of the present invention. Thesupport element 8 has the supportingstructure 10 and instead of flaps arranged on arms,spacers 15 extending radially outward. The inward orientatedarms 12 themselves disrupt the flow of water from the inlet to the outlet side. - Preferably, the
support element 8 is one piece, made out of steel sheets as a stamped-bent part. - In another preferred embodiment with no additional quartz sleeve being present, the inventive quartz sleeve support holds the quartz glass of the lamp directly. In this case the glass of the lamp is referred to as sleeve.
- The inventive quartz sleeve support is simple, easy to fabricate and thus cheap, and allows easy installation without any risk of breaking the sleeve.
